Trace element carriers in combined sewer during dry and wet weather: an electron microscope investigation.
The nature of trace element carriers contained in sewage and combined sewer overflow (CSO) was investigated by TEM-EDX-Electron diffraction and SEM-EDX. During dry weather, chalcophile elements were found to accumulate in sewer sediments as early diagenetic sulfide phases. The sulfurization of some metal alloys was also evidenced. Other heavy metal carriers detected in sewage include metal allo...
متن کاملUrban Wet - Weather Flows 1
INTRODUCTION 4 This subject, Urban Wet-Weather Flows, was comprised of three basic subareas – combined-sewer 5 overflows (CSOs), sanitary-sewer overflows (SSOs), and stormwater discharges. Major proceedings 6 related to wet-weather flow (WWF) published during 2000 were the following: (1) ASCE EWRI 7 Conference – Bridging the Gap: Meeting the World’s Water and Environmental Resources Challenges ...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Potential Human Health Effects Associated with Urban Wet Weather Flows
High concentrations of likely pathogens and indicator organisms found in urban receiving waters is a common cause of concern. Large amounts of resources are spent attempting to identify and correct their source, while many question the actual public health concerns associated with exposure to these organisms. This paper contains a summary of the historical development of the U.S. water quality ...
متن کاملMethods for Optimizing Urban Wet-Weather Control System
To minimize impacts of urban nonpoint source pollution and associated costs of control (storage and treatment) associated with wet-weather flows (WWFs), stormwater runoff volumes and pollutant loads must be reduced. A number of control strategies, so-called “best management practices” (BMPs) are being used to mitigate runoff volumes and associated nonpoint source (diffuse) pollution due to WWFs...
